Teacher Collaboration

I would really like to have a mentor teacher, if not two, that I could rely on in times of need. I would love to share ideas and methods, tests and worksheets. I would like it to be a mutual collaboration, meaning no one involved did any more work than the others. It would not be fair if one teacher created the tests for all teachers on that grade level. Collaboration means teamwork. Teamwork means equal contributions. If I want my students to work in cooperative learning groups in the classroom, collaborating with teachers would set a good example for them to follow.
